The gas supply to your home will either be Natural Gas 

or L.P. Your furnace is factory equipped to operate on 

Natural Gas. If your gas supply is L.P., you must contact 

a qualified serviceman or gas supplier to convert the 

furnace. Instructions for conversion to propane are shown 

on 

page 19

Factory installed orifice sizes are listed in 

Table 6, (page 17)

.

For natural gas operation, the maximum inlet pressure 

for the valve is 7” W.C and the minimum inlet pressure 

is 4.5” W.C. Pressure is reduced to 3 1/2” W.C. by the 

pressure regulator in the gas valve.
For LP gas, pressure to the gas valve must be more than 

11” W.C. but not more than 13” W.C. Pressure is reduced 

to 10” W.C. by the pressure regulator in the gas valve.

Leak Check

 WARNING:

FIRE OR EXPLOSION HAZARD

Failure to follow safety warnings exactly could 

result in serious injury, death or property 

damage.
Never test for gas leaks with an open flame. 

Use a commercially available soap solution 

made specifically for the detection of leaks 

to check all connections. A fire or explosion 

may result causing property damage, personal 

injury or loss of life.

•  Electrical Supply: 120 volts, 60HZ, 1 Ph. Fuse or 

Breaker - 15 amps

•  Temperature Rise: 45° F to 75° F

•  High Altitude for US and Canadian installations: 

See High Altitude  section on 

page 18

.

•  Thermostat Circuit: 24 volts, 60HZ, 30 vac

•  Normal Anticipator Setting: 0.4

•  Manifold Pressure for Natural Gas: 3.5” w.c.

•  Manifold Pressure for LP Gas: 10” w.c.

 AVERTISSEMENT :

RISQUE D’INCENDIE OU D’EXPLOSION

Le non-respect des avertissements de sécurité pourrait 

entraîner des blessures graves ou des dommages matériels 

importants.
N’effectuez jamais d’essai d’étanchéité des gaz avec une 

flamme nue. Utilisez une solution savonneuse offerte sur 

le marché conçue spécialement pour la détection des 

fuites pour vérifier tous les raccordements. Un incendie ou 

une explosion pourrait survenir et causer des dommages 

matériels, des blessures ou des pertes de vie.

•  The main gas valve and main power disconnect to 

the furnace must be properly labeled by the installer 

in case emergency shutdown is required.

•  Flexible gas connectors are not recommended for 

this furnace but may be used if allowed by local 

jurisdiction. Only new flexible connectors may be 

used. DO NOT reuse old flexible gas connectors.

•  Best practice is to use a drip leg for a vertical run 

to the unit.

•  All piping shall be black iron pipe. Internally tinned 

copper tubing may be used for gas supply systems.

•  Fuel line installations other than typical installations 

shown in 

Figure 27

 must comply with the fuel piping 

provisions stated in the Federal Manufactured Home 

Standard (H.U.D. TITLE 24, PART 3280) and the 

National Fuel Gas Code (ANSI-Z223.1/NFPA-54).

•  Shut-off valve must be designed and listed for use 

with liquid petroleum (L.P. gas).

• Plugged tappings (1/8” NPT) for test gauge 

connection are present on the gas valve. See 

Figure 

27

 for locations.

NOTE:

 Optional fuel inlet lines are available for all gas 

furnace models to permit the addition of a 1/2” F.P.T. 

shut-off valve above the floor.
